[cisco-voip] QoS for Day to Day traffic

[Kevin Dunn]

AHHHHHHH (light bulb moment)

by matching ACL 101 I am putting everything BUT 10.31.0.0 traffic in the
day2day class, and then everythign else would be in default class...  very
awesome.

and THAT is why I ask, because sometimes, you just don't think the way
everyone else does.

Thank you all very much.
